Protective member for automatic open close umbrella with anti-springing effect

Abstract

A protective device for automatic open close umbrellas is revealed. The protective device includes a ratchet mounted in a handle and rotating elastically for retracting or releasing a string, a string whose bottom end is fixed on the ratchet while a top end is fixed on an outer tube of an umbrella shaft or a core tube, and a locking member that is reverse L-shaped and is arranged with an elastic member for turning back therein. The locking member includes an upper part, a lower part, and a middle axle, used as a first-class lever. The upper part is against the bottom of the umbrella shaft so that the fastener can lean against a top surface of the upper part. When the umbrella shaft is gradually folded, the top surface of the upper part of the locking member is separated from the fastener while the bottom of the lower part is locked to one of the ratchet teeth of the ratchet elastically so as to achieve anti-springing effect.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to a protective member for automatic open close umbrellas, especially to a protective member for automatic open close umbrellas with anti-springing effect that prevents an umbrella shaft from springing back effectively when a force applied to the umbrella shaft disappears suddenly.[0002]The automatic open close umbrella available now opens and closes umbrella frames by pressing a button on a handle. While closing the umbrella, users need to slide down an umbrella shaft toward the handle so as to shorten the umbrella shaft to a locating point for being locked. That's the closed state. While during closing process of the umbrella shaft, the force applied to the umbrella shaft may suddenly disappear due to improper operations and the umbrella shaft is stretched out and users may get hurt. The followings are prior arts of protective members for automatic open close umbrellas.[0003]Refer to FIG. 1, a protective member for aut...

AI Technical Summary

Benefits of technology

"The present invention provides a protective member for automatic open close umbrellas with anti-springing effect. The invention includes a ratchet, a string, and a locking member. The ratchet with elastic member is mounted in a handle, and the string is wound around the ratchet elastically and fixed on the outer tube of the umbrella shaft. The locking member is formed by an upper and lower part, and a middle axle is set between them. The locking member pivots by the middle axle and is locked to the ratchet teeth of the ratchet elastically when the umbrella shaft is shortened. The invention simplifies the connection, structure, and movement among the ratchet, string, and locking member, increases strength, reduces cost, and increases safety and life. The string is fixed on the bottom end of a core tube in the umbrella shaft."

Problems solved by technology

Moreover, the fastener is not disposed with an insertion hole so that the tip thereof is not easily worn out.
